BULLETIN-BOARD.

SPECIFICATION forming part of Letters Patent N0. 762,666, dated June 14,1904.

Application filed August 27,1908.

To all whom it may concern.-

Be it known that I, ALIoE A. WALLMAN, a citizen of the United States ofAmerica, residing at New York,in the county of New York and State ofNewYork, have invented certain new and useful Improvements in Bulletin-Boards, of which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

The object of this invention is to provide a bulletin-board ordisplay-board for news or advertising purposes whereby the display ofnotices of various kinds may be read outside of a window in which theapparatus is placed and whereon such notices may be written or printedfrom within or at the back of the apparatus, a further object being toprovide such a bulletin or display board which may be used inconjunction with a type-writing machine operated out of the sight ofpersons reading the notices on said bulletin and also to provide such anapparatus which is simple in construction and operation andcomparatively inexpensive.

The invention is fully described in the following specification, ofwhich the accompanying drawings form a part, in which theseparate partsof the invention are designated by suitable reference characters in eachof the views, and in which 7 Figure 1 is a perspective front view of myinvention; Fig. 2, a perspective back view thereof and taken on the line2 2 of Fig. 1; Fig. 3, a section on the line 3 3 of Fig. 2; Fig. 4, aplan view of a part of the apparatus, taken on the line 4 4 of Fig. 3;Fig. 5, a front view of a carriage which I employ, taken on the line 5 5of Fig. 3; Fig. 6, a section on the line 6 6 of Fig. 1; Fig. 7, asection on the line 7 7 of Fig. 4:; Fig. 8, a detail view of a hangerwhich I employ; Fig. 9, a view similar to Fig. 4, but showing amodification thereof; Fig. 10, a section on the line 10 10 of Fig. 9;Fig. 11, an enlarged view of an escapement which I employ, and Fig. 12an enlarged view of an ink-roll which I employ.

In the drawings forming part of this specification I have shown a casinga, comprising a front, top, and side members,'the side mem- Serial No.170,902. (No model.)

bers of which are projected backwardly to form a support for a tablemember a which is about the same height from the floor as an ordinarydesk-top and which extends entirely across between the side members ofthe casing, and, as will be seen in Fig. 1, the front member of thecasing is provided with an opening (0 slightly less in width than thecasing 66-.

In the top of the casing a is detachable rod 5, adapted to receive aroll of paper 6 rotatably mounted thereon and extending nearly acrossthe casing, and the free end of the paper strip Z1 is passed downwardly,backwardly, forwardly, and upwardly and secured to a supplemental rod6", adjacent to the rod 6, and the paper strip is held in this positionby means of rollers 6*, L and b, and beneath the paper strip 6 andadjacent to the roller 6'' is a bar or plate V, which extends entirelyacross the casing a and is adapted to serve as a platen for the actionof the type of a writingmachine, afterward described.

Near the top of the opening a and within the casing a are twofriction-rollers o and 0 which hold the paper strip firmly between them,the roller 0 of which is provided with a shaft 0 which passes throughthe casing and carries a band-wheel or pulley c and ratchet wheel 0 withwhich a pawl c mounted on a crank-lever 0 is adapted to operate, thecranklever 0 being connected to a rod 0, which in turn is connected to ahand-lever c, and, as will be seen, when the hand-lever a is depressedthe pawl c and ratchet-wheel c operate to revolve the friction-roller c,and thereby the paper strip 6 is caused to move, this movement beingregulated to the desired space between two lines of printed matter onthe paper strip, and connecting the band-wheel 0* with a similar one, 6,on the shaft of the rod 5 isa belt I), which operates to turn the bar 6when the roller 0 is revolved; but as this movement increases as thepaper wound on the bar 5 increases the belt 6' is slack enough to permitsliding when the rotary movement of either of the bar 6 or roller 0 istoo great for the other one thereof, and by this means the paper stripis wound on the bar Z), whence it may be removed when entirely thereon.

In the form of construction shown in Figs. 1 to 7, inclusive, 1 mounttracks (Z on the table member a, and upon which is placed a carriage (Zprovided with wheels (1", and a rotatable disk d" is mounted upon a centally-arranged neck member (i of the carriage (Z the disk (Z' beingprovided with radial slots, thereby forming radial fingers d, upon thebottom of the end of each of which is secured a type (T, any one ofwhich when in its operative position is directly above the platen b andthe disk (7 is composed of spring metal, so that if any finger thereofbe depressed in the operation of forcing the type (Z into contact withthe paper strip above the platen b and thereby printing on said paper,the said finger (Z will resume its normal position upon being released,and secured to the carriage OZ is an arm (Z upon the end of which ismounted an ink-roll d, which bears against the'type (Z said type beinginked in the rotation of the disk d".

At the middle of the front portion of the carriage (Z 1 preferably mounttwo upright guides c, which prevent movement of the fingers (Z whenforced thereinto in the operation of printing, and pivotally mounted onthe carriage (Z is a lever as shown in Fig. 4, which is provided at itsouter end with a pawl 0 which engages the teeth of a rack a", mounted onthe table member a, and at the inner end of the lever c is a block,which is inclined on its face adjacent to the typefinger 0, againstwhich it is adapted to bear, and when said finger is depressed inwriting the lever c swung on its pivot and the pawl a passing over thenext tooth on the rack c", engages the same, the lever 6 being forcedinto its normal position by a spring a when released, this movementcarrying the carriage the distance of one tooth each time the lever isoperated, which corresponds to the spacing between letters in thewriting, and

the too free movement of the carriage is prevented by a spring-operateddrag a, operating in an undulating rack 0 secured to the table member cand the undulations of which correspond to the length of the teeth ofthe rack 0 In Figs. 9, 10, and 11 is shown amodification of thecarriage-operating mechanism last described, the tracks (Z and carriage(Z being substantially the same, but with the difference that the neckmember (Z is provided with a collar f, to which are secured agear-wheelf, engaging a rack f connected with the casing a, and aratchet-wheel f mounted thereover and with which a beveled arm of apivoted lever f is normally engaged, the other end of said leverextending to a point beneath the end of the finger d, which is inoperative position for printing and which is depressed when said fingeris depressed, and when said linger is released the lever is forced intoits normal pospring-operated drum 2 operates to draw the carriage to theright-hand end of the table member (4 as will be readily understood; butthe carriage is held in position by means of the rackf and thegear-wheelf said gearwheel not being able to revolve normally, becauseof the ratchet-wheel f and arm f of the lever f.

When in the operation of the apparatus the linger d is depressed, theouter end of the lever f is also depressed, the inner end f thereofbeing raised far enough to permit it clearing the ratchet-wheel f", atwhich time the pawl f engages the same tooth of the ratchet-wheel, andas the spring of the drum i is more powerful than the spring f 9 thecarriage is moved the distance of one tooth, which corresponds to thespace between letters, for the reason that the ratchet-wheel havingrevolved the distance of one tooth the gear-wheel f also moves thatdistance over the rack f", and in practice I provide a spacelinger d" tospace between words.

As will be seen, the operation of one of the lingers in the operativeposition for printing not only prints upon the paper strip above theplaten 6 but also automatically moves the carriage the distance of oneletter, and when the line of matter has been printed in this manner theoperation of the hand-lever 0" moves the paper strip the distancebetween lines of matter, and this operation being continued the printedmatter appears in the opening a of the casing 64 and may be read fromwithout, and when the paper strip is unwound from the feed-roll on therod band wound on the rod 6 the same may be removed and a new rollsubstituted therefor, the rods and rollers all being detachable from thecasing 64 by means of the hangers shown in Fi 8 of the drawings.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A bulletin-board, comprising a frame, a roll of paper in the topthereof, the free end of said paper being carried downwardly,backwardly, forwardly and upwardly, a rod in the top of said frame uponwhich the free end of said paper is wound, friction-rollers bearing onsaid paper adjacent to said rod, a pulley on said rod, a pulley on theshaft of one of said friction-rollers, a ratchet-wheel on saidlastassess named shaft, a pawl in operative connection therewith, ahand-lever in operative connection with said pawl, a belt connectingsaid pulleys and means for printing characters on said paper,substantially as shown and described.

2. A bulletin-board, a roll of paper mount' ed in the top thereof, saidpaper being carried downwardly, backwardly, forwardly and upwardly, arod upon which the free end of said paper is adapted to be wound,devices for movingsaid paper step by step, a platen mounted beneath thebackwardly-directed portion of said paper strip, rollers guiding saidpaper in said directions, and means for imprinting characters on saidpaper above said platen, substantially as shown and described.

3. A bulletin-board, comprising a casing, a baclnvardly-directed portionthereof adapted to serve as a table, an opening in the front of saidcasing, a roll'of paper in said casing and carried downwardly,backwardly, forwardly and upwardly to the rear of said opening, devicesfor moving said paper step by step, a platen beneath thebackwardly-directed portion of said paper, tracks laterally arranged onsaid table member of said casing, a carriage on said tracks, a rotatabledisk on said carriage, radial slots in said disk forming radial fingersor arms, a type at the end of each of said arms adapted to strike saidpaper above said platen, an ink-roll for said type and means for movingsaid carriage step by step substantially as shown and described.

4:. In a bulletin-board of the class described, a table, a plurality oftracks mounted thereon, a carriage on said tracks, a rotatable disk onsaid carriage, radial fingers or arms on said disk, a type beneath theend of each of said fingers, arack on said table, an undulating rackbetween said tracks, a spring-operated drag connected with said carriageand operating on said undulating rack, a lever pivoted on said carriageone end of which extends over said first-named rack, a pawl on saidlever acting on the teeth of said rack, a beveled block on the inner endof said lever adjacent to one of said fingers when in operative printingposition and the depression of which moves said lever radially,substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 22d day of August,1903.
